brew doctor error usr/bin before usr/local/bin

gistfile1.txt

ah ok thanks for explaining this.
.bash_profile now reads:
[[ -s ~/.bashrc ]] && source ~/.bashrc
and .bashrc like this:
export PATH=/usr/local/bin:/usr/local/sbin:~/bin:$PATH

echo $PATH gives me
/usr/local/bin:/usr/local/sbin:/Users/max/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin:/usr/local/MacGPG2/bin

chown and friends are now working again.
